PRINTING-MACHINE FOR DUPLICATING TYPE-WRITTEN WORK. I

SPECIFICATION forming part of Letters Patent No. 571,028, dated November10, 1896.

Application filed November 1, 1894:. Serial No. 527,619. (No model.)

To all whom it mwyc'onoern:

Be it known that I, GARRY P. VAN WYE, a citizen of the United States,residing at Chicago, in the county of Cook, State of Illinois, haveinvented a new and useful Improvement in Printing-Machines forDuplicating Type- IVritten York, for the purpose of printing letters,circulars, or any other printed matter where a number of copies arewanted and it is desirable that the printing should imitatetype-writing, of which the following is a specification.

My invention relates to improvements in printing-machines in which theprinting is done by means of a blow movement, either through an inkedribbon or otherwise, as it is evident that the form of type may be inkedby means of a roller or pad, as is now commonly done in otherprinting-presses and printingmachines. It is also evident that a machineadapted to print with a blow movement may be constructed in variousways, but the way I have found most convenient and suitable for thispurpose is a machine in which, first, a suitable arm and plate are soconstructed as to hold the paper on which the printing is to be done andadapted to be rocked back and forth by a suitable device, and soadjusted that the front of the plate may impinge against a form of type;second, a suitable arrangement for rocking the arm and plate so that theplate may be brought against the form of type with a blow movement andreturned so that the printed sheet may be taken out by the operator anda blank sheet inserted; third, a suitable cushion on the front of thesaid plate, preferably made of vulcanized rubber, to

somewhat soften the effects of the blow and produce an even impressionon all parts of the sheet in printing; fourth, a suitable device forholding the paper against the said cushion while being brought againstthe form of type and also while being returned 5 fifth, a suitable meansof adjusting the said arm and plate so that the said cushion will alwaysstrike evenly on the said form of type; sixth, a suitable device forholding an inked ribbon and permitting it to feed evenly and smoothlyover the form of type; seventh, a suitable device for feeding the saidinked ribbon over the form of type and so adapted that the ribbon may bereversed and fed across the type in the opposite direction after beingfed across in one direction. I attain these objects by means of themechanism illustrated in the accompanying drawings, in which- Figure 1is a side view in elevation of the entire machine. Fig. 2 is an end viewof the same. Fig. 3 is a plan view. Fig. 4 is a detail view of the camand lower extension of the rocking arm. Fig. 5 is another view of thesame with the cam and arm in a different position. Fig. 6 is a detailview of the ribbonfeeding device. Fig. '7 is a detail side view of thepaper-holding device, and Fig. 8 is another view of the same.

Similar letters refer to similar parts throughout the several views.

In Fig. 1, A represents the frame with legs suitably attached forholding the same in its proper position. Journaled on the top of thisframe in a suitable manner is the shaft N, on which is attached thebelt-pulley V, the flywheel \V, and the gear-wheel P. Onthe opposite endof the shaft N, and attached thereto, is the crank-arm Q, to which isattached in a suitable manner the rod R connecting the crank-arm Q. withthe foot-lever S, which is suitably attached to one of the legs of theframe A at U and bearing on the other end the foot-plate 'I. Thus itwill be seen that the printing-machine may either be operated by steam,electric, or other power in connection with the belt-pulley V,or byfoot-power in connection with the crank-arm Q. 8 5

The gear-wheel on the shaft N meshes with another gear-wheel O, which isattached to shaft M, the shaft M being suitably journaled on the frameA. On the opposite end of the shaft M is attached the cam J, which,together 0 with the shaft M, revolves in the direction of the arrow 1,Figs. 4 and 5. On the outer edge of the cam J revolves the small rollerL, attached in a suitable manner to the arm K, which is attached to theshaft F. The shaft 5 F is j ournaled in adjustable bearings, which maybe constructed in various ways, but for the purpose of my invention 1have chosen the way shown in Figs. 1, 2, and 3, in which the sliaft F isjournaled in the block II, which is Jheld in position by the guides Gand adj ustb .thcrein by means of the thumb-screw I,

for the purpose hereinafter set forth. Attached to the shaft F by meansof arms, as shown in Fig. 2, is the plate D. On the front of the plate Dis a cushion E, against which the paper rests while receiving the blowagainst the form C. This cushion or platen E should be firm enough togive an even impression over the whole form 0 without allowing the typeto cut or break through the pa per, and at the same time it should havea certain degree of elasticity, so as to protect the type as much aspossible. For the purpose of my invention I have chosen vulcanizedrubber as being most suitable for this purpose.

Attached to the frame A in a suitable manner is the inclined frame B,bearing a suitable bed, chase, and formterms in common use amongprinterswith suitable arrangements for holding the same. These parts arenot described here for the reason that they are in common use inprintingpresses and printing-machines now in use, but for the purpose ofconvenience we will designate the form as C.

To the plate D is attached in a suitable manner the arm e, and attachedto the arm 6 is the spring a, the other end of which is attached to therod d, on which is a thumb-nut c, which, in connection with the smallplate Z), attached to the frame A, forms a suitable combination forregulating the tension of the spring a.

It will be observed that the spring a is so placed as to exert aconstant force on the plate D and arm K, which is held in the positionshown in Fig. 1. by means of the cam J through the greater part of itsrevolution. IVhen the cam J in its revolution in connection with theshaft F reaches the position shown in Fig. 4;, it ceases to exert anyforce on the roller L on the arm K, whereupon the spring a draws theplate D forward on the form C with a blow movement, and at the same timethe arm K with the roller L rocks in the direction shown by arrow 2,Fig. 4c.

The force of the blow on the form C, it is evident, will be regulated bythe tension of the spring a.

\Vhen the arm K with small roller L has rocked a sufficient distance inthe direction of arrow 2, Fig. 4, to permit the platen E to impinge uponthe form C, the cam J will immediately take effect on the roller L,bringing it back in the direction indicated by arrow 3, Fig. 5, and theplate D back to the position shown in Fig. 1.

For the purpose of holding the paper against the platen E while beingprinted I prefer to use the mechanism illustrated in Figs. 7 and 8, Fig.7 being an end view and Fig. 8 being a sectional side view of the same.The mechanism consists of the shaft X, suitably journaled at each end ofthe plate D. The arms Y Y are held on the shaft X by means of thecollars Z and made rigid thereon by means of the set-screws Z X is thespring 7, which is also attachcclto Attached to the shaft the plate D ina suitable manner so as to.

hold the arms Y Y firmly against the platen E. Attached to the shaft Xis a small arm Z, to which is attached a cord Z, the other end of whichis attached in a convenient manner to some part of the frame A in such away as to raise the arms Y Y, as shown in Fig. 1, when the plate D isbrought back by the cam J, and thereby permitting the removal of theprinted sheet and the insertion of another sheet of paper.

The shaft F bears the plate D, and the bearings of the shaft F beingadjustable by means of the thumb-screw I, as hereinbefore set forth, itis evident that the platen E 011 the plate D may be so adjusted as tostrike a uniform blow on every part of the form C.

The blow movement I claim as an important part of my invention, becauseI have found by experience that there is a material difference betweenthe effect produced by a blow movement and that produced by pressure,the force now used in printing-presses. Especially is this the case inthe shade of color. I do not intend to limit myself to the mechanismherein described for the attainment of this result, as it is evidentthat it would be just as easy to bring the form of type againsttheplaten with a blow move ment, or that both should oscillate and meetwith a blow movement, in any case producing the same result induplicating typewritten work; nor do I intend to limit myself to the useof a spring for producing the oscillation of the platen or form, orboth, as there are other devices well known in mechanics which wouldproduce the same results.

As a means of inking the type I prefer to use an inked ribbon r, Fig.3,which is fed over the type or form and is wound on a ribbon-spool g ateither end of the said form, the said ribbon-spools revolving in thebearings h.

The device I have chosen for operating the ribbon-spools is that shownin Fig. 6. The wheel 1' is attached to the lower end of the shaftbearing the ribbon-spools g g. The casing is attached in a suitablemanner to the frame B, so that the plate D, or an extension thereof,shall impinge against the end of the pawlj as the plate D descendsagainst the form 0, driving the pawl j through, so as to engage anothertooth of the wheel 2', and when the plate D is raised by the cam J thespring at on the pawl j acts on the said pawl and brings it back to theposition shown in Fig. 6, and in so doing revolves the ribbon-spool, andthereby feeds the ribbon over the said form of type. The pin 15, workingin the. slot m, prevents the spring at from bringing the pawl j back toofar.

Having thus described the improvements, what I claim as my inventionis- 1. In a printing-press, a platen supported by a pivoted arm, acam-shaft and means for rotating the same, a cam on said shaft adaptedto engage said arm and suddenly release the same, and a spring to movesaid arm towardv the type.
